motikomisyuuri ga kanou desu.

持込修理 means carry-in repair or bring-in repair.

It refers to a type of repair service where the customer brings the item to the shop, counter, or service center. So it is not talking about the act of repairing something yourself; it is talking about a repair service method.

• 持込 = bringing something in
• 修理 = repair

So together, 持込修理 means repair done for an item that you bring in.

This is a very common question. 持込 is a shortened written form of 持ち込み.

The full form comes from the verb 持ち込む, which means to bring in. In compounds, especially in business writing, signs, forms, product labels, and service menus, Japanese often drops some hiragana and writes a more compact form.

So:

• 持ち込み修理 = full, more explicit form
• 持込修理 = compact written form

Both are read the same way here: もちこみしゅうり.

It is pronounced:

もちこみしゅうり が かのう です

Word by word:

• 持込修理 = もちこみしゅうり
• が = が
• 可能 = かのう
• です = です

In normal writing, there are usually no spaces:

持込修理が可能です。

Here, が marks the thing that is possible.

The basic pattern is:

Noun + が + 可能です
= Noun is possible / available

So:

• 持込修理が可能です
• literally: Carry-in repair is possible

This is a very common structure in formal or written Japanese.

Because 可能 does not work like an action verb that takes a direct object with を.

In English, you might think of something like We can do carry-in repairs, where carry-in repairs feels like the object. But in Japanese, this sentence is built differently:

• 持込修理 is the thing being described
• 可能です says that it is possible/available

So が is natural because the sentence is more like:

• Carry-in repair is possible not
• Someone does carry-in repair

If you used を, it would not fit this structure.

可能 is a na-adjective (also often described as a noun that can act adjectivally).

That is why it can be used like this:

• 可能です = is possible
• 可能でした = was possible
• 可能ではありません = is not possible

So in this sentence, 可能です is the predicate, meaning is possible or is available.

Both can often be translated with can or is possible, but the nuance is a little different.

• 可能です sounds more formal, written, and business-like
• できます sounds a bit more direct and conversational

So a company notice or service description often prefers 可能です.

Compare:

• 持込修理が可能です = Carry-in repair is available / possible
• 持込修理ができます = We can do carry-in repairs

The first sounds more like a service policy statement. The second sounds a little more like spoken explanation.

です makes the sentence polite.

Without it:

• 持込修理が可能だ = plain form
• 持込修理が可能です = polite form

This kind of sentence is very common in customer service, store notices, websites, and official information, so です is exactly what you would expect.

Yes. Japanese often omits information that is obvious from context.

This sentence does not explicitly say:

• who can do the repair
• what item is being repaired
• where the repair can be done

But in context, it usually means something like:

• We can accept carry-in repairs
• Carry-in repair is available
• This item can be repaired if you bring it in

Japanese often leaves those details unstated if the situation already makes them clear.

Yes, は is possible, but the nuance changes a little.

• 持込修理が可能です = carry-in repair is possible
• 持込修理は可能です = as for carry-in repair, it is possible

Using は can sound more contrastive or topical, as if you are distinguishing it from other options. For example, maybe mail-in repair is not available, but carry-in repair is.

Using が is a straightforward way to present the availability of that option.

No. Normal Japanese writing usually does not use spaces between words.

So the standard written form is:

持込修理が可能です。

The spaces in your example are probably there only to help learners see the parts more easily.
